ADOLF SCHWARTZ AND JACOB SCHWARTZ, OF BALTIMORE, MARYLAND.

HORSESHOE.

To all whom 'it may concern:

Be it known that we, ADOLF SCHWARTZ and JACOB SCHWARTZ, citizens of' the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification.

This invention relates'to an improvement in horse-shoes of that class that employ two parts, of which one may be termed permanent because it is nailed to the hoof of the animal, and the other part may be termed removable because it is mechanically attached to the nailed part and may be removed without disturbing the said nailed part.

The accompanying drawing shows the improvement.

Figure l is a plan view of the bottom side of the permanent or nailed part of the horseshoe. Fig. 2, is a plan View of' the bottom side of the removable part of a horseshoe, without the heel calks. Fig. 3 is a view of the complete shoe partly showing a side View and partly a vertical section on the line 3--3 of Figs. l and 2. Fig. el is a vertical section through both parts of the toe of the shoe, on the line 4 4 of Fig. 2.

.The letter, A, designates the shoe-part that is to be nailed to the animals hoof; this upper part of the horseshoe has on its bottom side the usual grooves, and nailholes, c. At each of the two heels, this part `of the shoe has a hole, d, that is screwthreaded; at the toe it is provided on its upper flat side, f, with an upward-projecting tang, e, and a screw-threaded -hole, g, passes through the toe-part just back of said tang. The permanent part, A, also has a suitable number of screw-threaded holes, h.

The removable or lower part, I, of the shoe is seen separately in Fig. 2; if this part as seen in Fig. 2 should be lifted bodily and placed upon the part, A, as seen in Fig. l, the two parts, A, and, I, would have their appropriate position. The lower part, or sole part, I, has a toe-calk, y', and immediately above this calk on the upper side of part, I, is an upward-projecting screw-bolt, 7c, that enters the screw-hole, g, in the part, A.

A hole, Z, is in each heel end; and between the heel ends and the toe-call( the lower part, I, has holes, m, that are counter-sunk on the bottom side.

Specification of Letters Patent.

Application filed March 21, 1910.

Patented Sept. 13, 1910.

Serial No. 550,587.

Two heel-calks are provided,-one designated, a, andY the other, o, each having a screw-bolt, y), that enters the smooth hole, Z, in the part, I, and the screw-threaded hole, (I, in the part, A. The two heel-calks are unlike in shape and function; the one designated, fn., is in the forni of a square block, and the other designated, 0, at its upper base is square but below said base the sides are beveled to produce a taper.

In applying this two-part shoe to the hoof of an animal, the part, A, is first secured to the hoof' by means of nails Whose heads must be small enough to take position within the groove, 1),' the sole part, I, is then taken in hand, and the screw-bolt, it', is entered in the screw-hole, g, and with the bolt, r, acting as a pivot, the said sole part is turned bodily around in order that the said screw-bolt will completely enter the said hole, g. lVhen thus screwed up until the top surface of part, I, is in close contact with the bottom surface of part, A, small screws, (1, should be ent-ered into the counter-sunk holes, m, and also into the holes, z. The heel-calks are then secured by their screw-bolts, p, entering the holes, Z, and, el, respectively, in the heel-ends.

The object in having on one heel-end of a shoe a different heel-call; from that on the other heel-end of the same shoe is to allow of one call; being tapered in order to more readily enter small crevices in the street pavement and thereby prevent the animal from slipping, while the other calk may be blunt and resist the tendency to wear. The shoe on a left f'oot should have its outer heel-end provided with the tapered heel calk, o, while the inner heel-end should have the blunt calk, 11'. The same is true of a right foot. By observation it has been found that some animals in pulling put more strain on the outer side of their feet. Of'

course the heel calks being detachable from Having thus described our invention what A we claim and desire to secure by Letters Patent is,-

A two-part horse-shoe having in combination a permanent part, A, to be nailed to the animals foot and the toe of which is provided with a screw-threaded hole, g, and each heel of which has a screw-threaded hole; and a removable part, I, of the same size and configuration as the said permanent part and Whose toe has on its lovver side a ealk, j, and on its upper side immediately above said Call; is provided With an upward-projeoting screw-bolt, lv, which lits 5 into said screw-threaded hole in the permanent part and at its heel ends has smoothbore holes which are coincident With the screw-threaded holes in the permanent part, and heel-calks each having a screw-thread- 10 ed bolt Which engages the holes in the heels of both the said removable and permanent parts.

In testimony whereof We aHiX our 'signatures in presence of tWo Witnesses.
